FR-S, GT86, 86, BRZ exhaust manifold UPDATE: Tip of the hat to MotoIQ Nerd @Jamal, who pointed us to Hellafunctional, who stole this image from someone over at FT86Club who snapped this shot in the Subaru booth at the Tokyo Motor Show a few days ago . Looks like the engine uses a proper 4-2-1 header, which means it will sound like a proper 4-cylinder, not like a WRX. Love that fact or hate it (I'm on the fence) this manifold is surely a large part of why this engine is capable of 100 hp per liter.


Subaru BRZ Turbo, toyota 86 turbo, scion fr-s turbo MORE UPDATES: Jay Kavanagh over at InsideLine.com posted these pictures of the Subaru 1.6 turbo sitting right next to the BRZ/86/FT-S engine. Though there are no claims this will go in the 86, it doens't take much imagination to see it being done, either by them or by us. This turbo packaging is very friendly for the 86's FR layout, since there will be tons of room in front for a bigger turbo. This packaging makes a twin-scroll a no-brainer, since you could essentially have the same manifold as the non-turbo engine, but with a turbo flange right after the 4-2 collectors. It would also be much easier to simply put the intercooler in front, where it belongs, and connect to the already forward-facing throttle body.

It's not clear how Subaru is dealing with oil drainage, since the turbo's oil drain is down below the oil line in the pan, but the fact that Subaru already worked it out for us makes it much easier when we turbocharge one of these ourselves.

The dual direct/port injection system now makes perfect sense. It's easier for tuners to leave the direct injectors alone and add bigger port injectors for boosted fueling.

Thread over.
